Karambolista, I guess the people who use the cross-over bridge are comfortable with its feel. I've tried it a couple of times and never liked it.
I have a lot of different feels with my bridge hand. A lot of my shots, I use my bridge hand to help me shoot the balls in accurately by maneuvering it in a lot of ways. It enables you to develop your correct feels for each shot. Sometimes it's looser, and other times, it's firm.
